Valid case:
1) If the offset is more than current fragment length, adjusts offset
from next relevant fragment and starts reading or skipping.
2) If the read or skip length is more than available data length,
then throw an error.
In case of an error, frag is 'NULL' pos is '0xffff'. Rest of the cases
are successful read and skip.

The legacy stack has all the net_context API stuff in
net_socket.h so include it in net/net_context.h file.
This re-works the commit 627feb92d4 which added the
net_context_get_internal_connection() to net_context.h.
Now that function prototype is found in net_socket.h.

This commit adds support the DNS client API on top of the new
native IP stack. Some features of this implementation are:
- Support for IPv4 and IPv6
- Support for multiple concurrent queries. A net_buf structure is
required per context. See the DNS_RESOLVER_ADDITIONAL_BUF_CTR
configuration variable

- we have a structur as callback so let's type the handler as a handler

Helper functions to read and write data across multiple fragments.
Write function always adds at the end of last fragment. If there is
no space in last fragment new data fragment will be created and added
to input buffer.
Read function start reading from offset of input fragment. If the
required data is located in mutliple fragments it reads from list
of fragments and returns position and fragment where read stopped.
Skip function start skipping from offset of input fragment. If the
required length is across multiple fragments it skip till length and
returns position and fragment where read stopped. This is useful
when reading with unwanted data (reserved or unhandled data).
These functions are quite useful when handling with multiple fragments.

If the connection establishment has an error, the accept
callback needs to be able to return that error to user space
so that the application can know about it.
This is especially important in TCP where application needs
to start to listen again if reset is sent during connection
establishment.

interfaces configured, then the second interface will point

hardware.

At some point such parameter could be changed to a void pointer,

specific struct or else).
Also make sure we use ARG_UNUSED() relevantly, and using proper prefix
